The Season 4 premiere of "Mistresses" is days away and while we wait for the drama to unfold, here's what fans can expect: Episode 1 of the latest season will expose some very troubling problems in Joss and Harry's relationship.

Although Savi would think otherwise, Joss and Harry actually make a great couple. He stood by her when she was in jail, but it remains to be seen if they can get over the traumatising incidents they had to face in the Season 3 finale.

Fans of the show will remember that Joss was hounded by Calista's (Jennifer Esposito) assistant, Wilson (Jarod Joseph) and almost lost her life. The trauma of his incident will affect her even after a year. This is evidenced in a recently released promo video.

In the sneak peek clip, Joss is seen walking towards her house when she finds it unlocked. She calls 911 in a state of panic and says, "I think someone's broken into my house. I don't know if they are still here but can you please send the police?"

However, the scene could just be a tease. It could very well be her boyfriend Harry, who is seen wearing the same T-shirt in another promo. According to the synopsis for episode 1 (via Carter Matt), the chef will find Joss withdrawn. His overtures will elicit a response that's not exactly romantic. The past clearly affects Joss and it remains to be seen if they can move beyond the ghosts of their past.

"Mistresses" Season 4 airs on Monday, May 30 at 9 p.m. EST on ABC. You can stream the episode via ABC GO.
